To all whom comer-n:

Be it known that I, GEORGE H. IsLEY, a

citizen of the United States, residing at Worcester, in the county of Worcester and I Commonwealth of Massachusetts,.llave invented a new and-useful Improvement in Gas-Producers, of which the follow ng, together with the accompanying drawing,

j is aspeoification. ,My invention relates-to gas producers and more artieularly to the be per or mechanism or supplying fuel to t e roducer.

One object of my invention 1s to provide an improved form of fuel feedingmecha- 16 nism' so arranged and constructe that .it will 5 read the fuel evenly and uniformly over the fuel bed.

Another object is to provide adjusting cans to correct .the operation of the .feedg mechanism if it is found, at anytime, that the fuel is not being spread evenly.

Another ob'ect is to provide adjusting means to regulate the rate of supply of the fuel in accordance with the rate of con- 26 sumption thereof in the producer.

. Further objects and advantages will appear from the following description taken inconneotion with the accompanying drawing, inwhich Figure 1 is a vertical sectional S0 view'of the upper portion of one form of gas producer constructed in accordance with my nvention; Fig.=2 is a vertical sectional view of the upper portion of a producer embodying a modified form of the invention; Fig. l 85 .3 1s a view' of a portion ofEig. lfbut wlth the lower section of the hopper in a difi'erent position of adjustment; and Fig. 4 is a plan view of the hopper. Similar reference characters refer to similar parts in the different figures.

In the 'form of the invention shown in Fig. 1, the. gas producer includes a stationary upper section 1 and a rotatable fuel section 2,1there being a water sealed oint 3 be- .46 tween the sections. The rotatable section 2 may be rotatably supported in any suitable, manner so that it may be rotated by the worm gear 4 which engages the circular rack 5 encircling the rotatable section. It

of the producer carryingthefuel feedin mechanism be stationary, as shown, .Itwi

be obvious as the d escription proceeds, however, that the sat 1e results would be ob tained by rotating either of the sections relatively .to the other. The top 6 of the upper stationary section l is provided with an opening 7 for my improved feeding mecha nlsm, this opening being offset toward one side of the produr er,

The'feeding mechanism includes hopper composed of an upper section 8 and a lower section 9. The lower end of the section 8 is contracted in the usual manner and. preferably extends, slig htly into the upper endi of-the section 9 so hat none of the fuel (le scending through the hopper can pass through the joint letween the two sections. The section Set the hopper is provided with. a flange 10 by mears of which it is mounted in register with the opening 7. The section 9 of the hopper is suspended by three bolts 11 spaced equally about the hopper. These or Wings 12 integral with and projecting from the periphery of thesection 9 of the the weight of the l olts 11 and the mechanism supported the reby.

.ment with the bolts so The .nuts 14 are more or less elongated. so that they may extend beyond the end s of the bolts to contact with the seatslii, the seats 15 being in aline and the section 9 of the hop er rigidly in place. The opposing forces 0? the two nuts on each bolt serve it rther to lockthe nuts in placeso as to prevent accidental change in adjustment thereof.

The space below t 1e discharge opening 16 of the section 9, wlzioh openin is also of course, the discharge o'penmg o the ho per use whole, has a sup porting shelf or tablia 1.7 to receive the fuel as it is discharged from the hopper. This t: ible one side of the producer in a position approximately concentric with the vertical axis of the hopper as a whole, but with t 1e outer edge of sa d'shelf more nearly beneath the discharge opening ]6 than the inner edge and it is supported'b 5 three hollow 18 depending from some suitable fined porfixedly upon the to p 6 of the producer and colts are attached a; their lower ends to cars supports as to hold the bolts I 17 is offset toward 40 resides 50 thefuel would be caused tions of the frame of the producer. In order to prevent injury to theshelf 17 by the heat generated in %he producer, the shelf is provided with a h ,llow' space 19 to accom 'modate a cooling current of water, a sup 'ly pipe 20 conducting the water to the i101 ow shelf and a discharge ipe 21 conducting the water from the shelf after it has become heated. The pipes 20 and 21are preferably 'located in the hollow supports 18 m order .togive thepipes as much protection as possible from the suyroundinglheat. t

The scraper 22, composed of horizo'ntalrotatable arms, is located-in the space between 5 the shelf and the bottom of the hopper and preferably close to, or in contact with, the top of. the shelf.- The scraping arms are carried upon a vertical shaft 23 pivoted near its lower end in a bearing at the center of the shelf and at its upper end in abearin in the upper portion. of the hopper. The s aft 23 and the scraper 22 are driven by a drivingshaft 24, the two shafts being connected by a-pair of bevel gears 25 and 26. The 25 driving shaft 24 is actuated by a pawl 27 and ratchet 28.. A The upper rim 29 of the hopper is pivoted at its center and has a floor 30 provided with openings 31. The pivoted handle 32, when go raised into a horizontal position, serves to rotate the rim 29 and its floor about its vertical axis to bring the openings 31 into register with cooperating openings in the top 33 of. the section 8 of the hopper so that fuel 35 which has beenplaced inside the rim29 may drop through the openings and thence downwardly ontothe shelf and into the path of the scraper 22.

One important feature ofthe invention in the fact that the discharge opening 16 ofthe hopper isoffset toward the outer edge of the shelf 17 or, in other Words, that it is eccentric with relation to the shelf. The arms of the scraper 22 rotate about a vertical axis at the center of the shelf and it isobviousfthat, if the discharge opening of the hopper were con-v centric with the axis of thejscraper so as to I deposit the fuel centrally 'upon the shelf, to pass uniformly over all portions ofzthe edge of the shelf. As thesectlon 2 of the producer rotates, how- .ever, the center of the-surface of the mass of fuel 34 moves much more slowly than do the outer portions of its surface, with the obvi' ous result that a considerably greater quantity of fuel would be deposited upon the central portion of the surface .of the fuel than upon itsouter portions i By arranging so the lower end of the hopper and its dlscharge opening 1 6 eccentrically with relatio". to the sheifi? and toward the outer edge thereof-g the fueli is deposited upon the Shel nearer to'the'outer than to the inneredg'eso thatthe scrapeif'will cause greater quantities of fuel the more rapli of the hopper is effected :by adjusting) above ,or below. its,-othe r'si d'e, $8

The ld wer section. 9 with the discharge opening 16-0! the hopper is, therefore, arranged to'be vertically adjustable to and from the shelf17 for the pur-' pose of varying the-rate at; which the fuel .willbesupplied to the. producer. It is clear that as thesection 9 of. theho I r is moved upwardly away from ,the s so as to' increase the space between t em'in which'the scraper 22 rotates, the fu' 11 will naturally spread out into a wider oi ole upon the shelf or, in other words, a eater q antit of fuel will lie in the path ff them; of the 1 scraper at any instant 0 time s, that the rate at which-fuel is cause topas over the edges of the shelf by th' scra or is increased.

ortion Io he y g-undet-t elowestY m/ menses I In the modified form of the invention shown in Fig. 2 of the drawing, the general construction is similar to that indicated in Fig. 1 and the same reference characters are similar 'parts except that in characters are primed.

used to indicafte Fi 2the re erence In ig. 2 the hop er 15 shown as constructed with an interme iate section supported from fixed portions of the frame-by bolts 11' so as 'to be vertically adjustable in the same manner-and for the same purpose as described in connection with the structure shown in Fig. .1. The lower section 9 of .the, hopper is suspended from the intermedldfl section .35 by three links 36, ivotally. corrhected at their upper ends-to t e intermediate section 35' andrht their lower ends to the lower section 9' of the hop er. This three point suspension by means 0 pivotally connected links allows the lower section 9' together with the discharge openin 16' of the hopper to move freely in any irection in a substantially horizontal plane. Three bolts 37 with their nuts 38, spaced egually about the section 9 of the hop or an conand to the fixed frame at their outer ends constitute means for adjusting the horizontal position of the lower section and the discharge openany desired I but having described claim as .new and desire ing of the hopper and for holding them in adjusted position. Ordinarily the desired degree of offset of thedischarge opening of the hoppertoward the outer edge of the shelf may be predetermined so that no adjustment is necessary in order to se cure fairly even distribution. ofjth'e fuel.

By arranging the "lower section of the hopper so as Lo be adjustable horizontally, however a scum-ea. accurate distribution maybe obtained and this is often very desirable.

While 1 have shown and described the de tails of certain forms of my invention, I do not wish to be limited to such details as it is obvious that changes may be made within the scope of the appended claims without departing from the spirit of theinvention; my invention, what I to secure by Letters Patent is:
